The reverse osmosis membrane system is the most important filtration system for pharmaceutical purified water equipment, and its working performance is directly related to the final water production of the equipment
.
The following introduces the reasons for the decline in the performance of pharmaceutical purified water equipment and the detection and judgment methods
.
Figure 1 Jingderui purified water equipment 1.
When the pharmaceutical purified water equipment operates at low pressure, the performance of the reverse osmosis membrane will decrease
.
Solution: Debug and run according to the designed reference pressure standard
.
2.
When the membrane module is compressed in the pharmaceutical purified water equipment, the performance of the reverse osmosis membrane will decrease
.
When the system runs significantly above the reference pressure, the compaction of the membrane module will occur.
In this case, it can be solved by replacing the membrane module
.
3.
When the operating temperature of the pharmaceutical purified water equipment decreases, the performance of the reverse osmosis membrane will decrease
.
Solution: operate according to the design temperature reaching the standard 25 ℃
.
4.
When the oil substance is mixed into the pharmaceutical purified water equipment, the performance of the reverse osmosis membrane will decrease.
Therefore, pay attention to absolutely not allow the oil substance to enter the water supply to replace the membrane module
.
5.
When metal oxides and contaminants adhere to the membrane surface, the performance of the reverse osmosis membrane will decrease
.
In this case, the user should perform low pressure flushing daily
.
6.
When the reverse osmosis membrane of the pharmaceutical purified water equipment is blocked, the performance of the reverse osmosis membrane will decrease
.
Detection method: Turn off the pressure bucket and observe that the water from the faucet can form water flow.
If the water flow cannot be formed, it means that the membrane element has been blocked, and the membrane element needs to be cleaned at this time
.
The decline of the water production and the deterioration of the water quality of the pharmaceutical purified water equipment will affect the production progress.
Therefore, the equipment management personnel need to find out the cause of the failure in time and formulate corresponding solutions to restore the performance of the equipment after maintenance
